File Names and Process Identifiers
This appendix summarizes the syntax for file names and process identifiers. It is in
four principal subsections.
The first subsection specifies reserved file names.
The second subsection describes the syntax that HP recommends for all new
development. Any system procedure that has a name ending with an underscore ( _ )
expects this syntax when you specify a file name or a process identifier as a
parameter.
The third subsection describes the syntax that is supported in C-series software and is
still supported in some system procedures in subsequent RVUs. Most of the
procedure calls that support C-series file name syntax are marked in this manual as
“superseded” and are listed in Appendix G, Superseded Guardian Procedure Calls and
Their Replacements .
The fourth subsection describes the syntax for OSS pathnames.
Reserved File Names
Subvolume names and file names beginning with the letter “Z” are reserved. You
should not choose such names in your application.
Syntax
This subsection summarizes the syntax for file names and process identifiers. It
describes the syntax for four categories of file names along with file-name patterns and
process handles. The four categories of file names are:
•
Names that identify disk files
•
Names that identify nondisk devices
•
Names that identify unnamed processes
•
Names that identify named processes
There is no distinction between external and internal file names. The system does not
distinguish between uppercase and lowercase alphabetic characters in a file name. If
all the optional left-hand parts of a file name are present, it is called a
fully qualified
file name; if any of the optional left-hand parts are missing, it is called a
partially
qualified file name.
